SPC Mesoscale Discussion: Severe Potential… Watch Possible

| December 2, 2018 @ 2:04 am

SUMMARY…Periodic supercells with a threat of damaging wind or a tornado remain possible this morning across southern Georgia and possibly points southwest, and an additional tornado watch may be needed.

DISCUSSION…A line of storms currently extends from the northern Gulf of Mexico across southeast AL and into southern GA near a warm/moist axis at 850 mb, and oriented nearly parallel to the mid/upper flow. Surface analysis shows relatively cool air over southeast GA as a result of outflow from earlier storms, with southwesterly surface winds aiding airmass recovery into southwest GA. Indeed, supercells were recently noted near the Albany GA area, near where the air mass is recovering and just west of the cooler/more stable air mass. Given persistent southwest flow in the low levels, additional airmass recovery may occur across the remainder of southern GA tonight. Little change is expected overall in the wind fields as 40-50 kt 850 mb flow persists, with around 50 kt midlevel flow. Sufficient veering with height will maintain favorable effective SRH within a sufficiently unstable air mass, with isolated severe storms possible.
